Briggs then shot and killed one of the toll collectors, Danny Crouse, who had been on the job for less than three months, and Ronald Heist, a retired York police officer who was employed by a detective agency and was working as turnpike security, Capt. David Cain said.
Briggs then fired at the fare collection vehicle, Cain said, and after the driver fled he jumped into the vehicle and drove it to his car, which was parked at the end of a service ramp a few hundred yards away. He started unloading money from the collection vehicle, Cain said.
Troopers arrived within minutes, and the first trooper exchanged shots with Briggs, who was wounded and died at the scene, police said.
